personally i would go with your original choice of super silver haze. in a SOG you can stop it from stretching by putting out the light for 72 hours and this will enduce flowering much faster and keep height down to a minimum.
i suggest doing a sea of green method works best for sativa's to keep them short. Also turning out the light for 72 hours at the begining of flowering will induce flowering much faster and stop it from stretch.
Thinking about getting himalayen gold from greenhouse seeds, anyone every try it before?? any coments about greenhouse seeds?? all opinions are welcome:bigjoint:
